OK. I've decided to integrate a OBDII reader to my carputer. I have an Oldsmobile Alero -99.
But as I see it there are three readers too choose from. Autotap, scantool or OSBdiagnostics. I want a reader that can work embedded in frodoplayer or mediacar (when that's possible), so I think Autotap is out of question. So there's still Scantool or OSBdiagnostics.
But Scantool seems to complicated with the 3-combo. So there's just OBDdiagnostics.
Is this correct or have I forgot anything?

OBDdiagnostics has the lowest price also ; ) ($98 to Sweden if I got it right)
